1. General description
The I•CODE SLI-L/I•CODE SLI-L HC IC is a dedicated chip for smart label applications with the need for a leaner custom-specific command set, smaller memory and/or a product which takes care of the increasing demand for perfect customer privacy. This IC is another member of our product family of smart label ICs that fully comply to the ISO standard ISO/IEC 15693. The IC is also available in high capacitance version for small label designs.
The I•CODE system offers the possibility of operating more than one label simultaneously in the field of the reader antenna (Anticollision). It is designed for long range applications with a special command for the use under the European regulations.
1.1 AnticollisionAn intelligent anticollision function allows to operate more than one tag in the field simultaneously. The anticollision algorithm selects each tag individually and ensures that the execution of a transaction with a selected tag is performed correctly without data corruption resulting from other tags in the field.
1.2 Contactless energy and data transferWhenever connected to a very simple and cheap type of antenna (as a result of the 13.56 MHz carrier frequency) made out of a few windings printed, winded, etched or punched coil the I•CODE SLI-L/I•CODE SLI-L HC IC can be operated without line of sight up to a distance of 1.5 m (gate width). No battery is needed. When the smart label is positioned in the field of an interrogator antenna, the high speed RF communication interface allows to transmit data with up to 53 kbit/s.

1.3 Security and privacy aspects
1. Unique Identifier (UID)The UID can not be altered and guarantees the uniqueness of each label.
2. Password protected Label DestroyWith the 32-bit destroy password an addressed label can be destroyed with the Destroy command. That status is irreversible and the label will never respond to any command again.
3. Password protected Privacy Mode With the 32-bit Privacy password a label can be set to the Privacy mode with the Set to Privacy Mode command. In that mode the label will not respond to any command except of the command Get Random Number till it receives again the right Privacy password. That mode is especially designed to meet the increasing demand to take care of the customers privacy.
4. Password protected EAS FunctionalityWith the 32-bit EAS password the addressed label can be set in a mode that the commands Set EAS and Reset EAS are only executed by the label if the right EAS password is transmitted to the label within the mentioned commands.

4. Quick reference data
The data sheet describes the functionality of the smart label ICS I•CODE SLI- L and I•CODE SLI- L HC. These ICs distinguish between the built in resonance capacitance. The I•CODE SLI- L HC shows a higher capacitance value than the I•CODE SLI- L. Therefore within the I•CODE SLI- L HC smaller label designs can be realized.

6. Block diagram
The SL2 ICS50/SL2 ICS51 IC consists of three major blocks:
Analog RF Interface
Digital Controller
EEPROM
The analog part provides stable supply voltage and demodulates data received from the reader for being processed by the digital part. Further, the modulation transistor of the analog part transmits data back to the reader.
The digital section includes the state machines, processes the protocol and handles communication with the EEPROM.

7. Functional description
7.1 Block descriptionThe label requires no internal power supply. Its contactless interface generates the power supply and the system clock via the resonant circuitry by inductive coupling to the interrogator. The interface also demodulates data that are transmitted from the interrogator to the I•CODE Label, and modulates the electromagnetic field for data transmission from the I•CODE Label to the interrogator.
Data are stored in a non-volatile memory (EEPROM). The EEPROM has a memory capacity of 512 bit and is organized in 16 blocks consisting of 4 bytes each (1 block = 32 bits). The higher 8 blocks contain user data and the lowest 8 blocks contain the unique identifier, the write access conditions and special data like AFI and DSFID.
7.2 Memory organizationThe 512 bit EEPROM memory is divided into 16 blocks. A block is the smallest access unit. Each block consists of 4 bytes (1 block = 32 bits). 4 blocks are summed up to 1 page. Bit 0 in each byte represents the least significant bit (LSB) and bit 7 the most significant bit (MSB), respectively.
The Memory is divided into 2 parts:
• Configuration Area– Within this part of the memory all required information are stored like UID, Write
protection, Passwords and so on. Direct access to this memory area is not possible.
• User Memory– Within this area the user data are stored. Direct Read/write access to this part of
the memory is possible depending on the related write protection conditions.

7.2.1 Unique identifierThe 64-bit unique identifier (UID) is programmed during the production process according to ISO/IEC 15693-3 and cannot be changed afterwards.
The numbering of the 64 bits is done according to ISO/IEC 15693-3 starting with the LSB 1 and ending with the MSB 64. This is in contrast to the general used bit numbering within a byte (starting with LSB 0).
The TAG type is a part of the UID (bit 41 to 48, after the manufacturer code which is “04h” for NXP Semiconductors).
7.2.2 Configuration of delivered ICsI•CODE SLI-L/I•CODE SLI-L HC ICs are delivered with the following configuration by NXP Semiconductors:
• Unique Identifier is unique and read only• Write Access Conditions allow to change user blocks, AFI, DSFID, EAS and
Passwords• All password bytes are 00h ( Privacy Password, Destroy Password, EAS Password)• Password protected Privacy Mode is disabled• EAS password protection is disabled• Status of EAS mode is not defined• AFI is supported and not defined• DSFID is supported and not defined• User Data memory is not defined

8.1.3.7 Inventory page readCommand Code = B0h
When receiving the Inventory Page Read request, the I•CODE SLI-L/I•CODE SLI-L HC IC performs the same as in the anti-collision sequence, with the difference that instead of the UID and the DSFID the requested memory content is re-transmitted from the I•CODE SLI-L/I•CODE SLI-L HC IC.
If an error is detected the I•CODE SLI-L/I•CODE SLI-L HC IC remains silent.
If the Option flag is set to 0 n pages of data including page protection status (password protection condition) are re-transmitted. If the option flag is set to 1 n pages (4 blocks = 16 byte) of data including page protection status (password protection condition) and the part of the UID which is not part of the mask are re-transmitted.
The request contains:
• Flags• Inventory Page Read command code• IC Manufacturer code• AFI (if the AFI flag is set)• Mask length• Mask value (if mask length > 0)• First page number to be read• Number of pages to be read• CRC 16
The meaning of flags 5 to 8 is according to table 5 in ISO/IEC 15693-3.
The number of pages in the request is one less than the number of pages that the I•CODE SLI-L/I•CODE SLI-L HC IC returns in its response.
If the Option flag in the request is set to 0 the response contains:

The I•CODE SLI-L/I•CODE SLI-L HC IC reads the requested page(s) including page protection status and sends back their value in the response. Additionally the bytes of the UID, which are not parts of the mask and the slot number in case of 16 slots, are returned. Instead of a padding with zeros up to the next byte boundary the corresponding bits of the UID are returned. The mechanism and timing of the Inventory Page Read command perform the same as at the Inventory command which is described in Clause 8 of ISO/IEC 15693-3.
The requested page(s) are transmitted in the following format and repeated as necessary (depending on number of pages):
Table 30. Page Protection Status bytePage Protection Status Byte Block Data00h: OK 16 byte page data content
0Fh: ERROR no data
Remark: The number of bits of the re-transmitted UID can be calculated as follows:
• 16 slots:– 64 to 4 - mask length rounded up to the next byte boundary
• 1 slot: – 64 - mask length rounded up to the next byte boundary

When receiving the Fast Inventory Page Read command the I•CODE SLI-L/I•CODE SLI-L HC IC behaves the same as in the Inventory Page Read command with the following exceptions:
The data rate in the direction I•CODE SLI-L/I•CODE SLI-L HC IC to the interrogator is twice as defined in ISO/IEC 15693-3 depending on the datarate_flag 53 kbit (high data rate) or 13 kbit (low data rate).
The datarate from the interrogator to the I•CODE SLI-L/I•CODE SLI-L HC IC and the time between the rising edge of the EOF from the interrogator to the I•CODE SLI-L/I•CODE SLI-L HC IC remain unchanged (stay the same as defined in ISO/IEC 15693-3).
In the direction I•CODE SLI-L/I•CODE SLI-L HC IC to the interrogator only the single subcarrier mode is supported.

8.2 Long range command
8.2.1 Long Range CMDCommand Code = 40h
The Long Range CMD command is designed to allow the use of the higher limits defined in the ISO/TR 7003:1990. The bit and byte coding is the same as it is defined in EPC Specification “13.56 MHz ISM Band Class 1 Radio Frequency (RF) Identification Tag Interface Specification”.
To reduce the number of pulses the redundancy check is changed from an CRC8 calculation to a XOR of the transmitted parameters (Long Range CMD, Data Selector, Number of Slots)
• Number of Slots:– If the Data Selector is transmitted for EAS the label will ignore the received
Number of Slots parameter and will use always one Slot (like EAS Alarm command, see Section 8.1.3.12 “EAS Alarm”). with EAS. For EAS typically 00h is used as the value for Number of Slots to reduce the number of transmitted pulses.
– If the Data Selector is transmitted for UID or EPC the label will respond within one of the transmitted Number of Slots on a pseudo random basis and will calculate a new slot for a following command.
Labels, which have executed a Destroy EPC command before will not respond to this command, if the Data Selector for EPC is transmitted.

8.3.2 Not supported commands or optionsIf the received command or option is not supported, the behaviour of the Label IC is depending on the addressing mechanism.
8.3.2.1 Non addressed modeThe label IC remains silent.
8.3.2.2 Addressed or selected modeThe addressed or selected label IC responds with the error code “0Fh” (error with no information given or error code is not supported).
If the Inventory flag or the protocol extension flag is set the label IC will not respond if the command or option is not supported.
8.3.3 Parameter out of range
8.3.3.1 Read commandsIf the sum of the first block number and the number of blocks exceeds the total available number of user blocks, the number of transmitted blocks is less than the requested number of blocks, which means that the last returned block is the highest available user block, followed by the 16-bit CRC and the EOF.
8.3.3.2 Write and lock commandsIf the address of a block to be written does not exist or a block to be written is locked the behaviour of the Label IC is depending on the addressing mechanism.
8.3.3.3 Non addressed modeThe Label IC remains silent and aborts the command without writing anything.
8.3.3.4 Addressed or selected modeThe addressed or selected Label IC responds with the error code “0Fh” (error with no information given or error code is not supported).

8.4 Data integrityFollowing mechanisms are implemented in the contactless communication link between interrogator and label to ensure very reliable data transmission:
• 16-bit CRC per block• Bit count checking• Bit coding to distinguish between “1”, “0” and no information• Channel monitoring (protocol sequence and bit stream analysis)
8.5 RF interfaceThe definition of the RF interface is according to the standard ISO/IEC 15693-2 and ISO/IEC 15693-3.
